| 摘 要： | 根据健康成人和胰腺外分泌功能不全(exocrine pancreatic insufficiency, EPI)人群的肠道条件,设置不同的胆盐浓度、肠道pH和胰脂酶浓度,分析加工山核桃基质降解率(matrix degradation rate,MDI)、脂肪和蛋白质消化率、总酚和抗氧化活性,探究不同肠道条件和粒径大小对加工山核桃体外消化的影响。结果显示,粒径大小对加工山核桃体外消化影响最显著,小颗粒加工山核桃MDI、抗氧化活性以及脂肪和蛋白质消化率均高于大颗粒加工山核桃。pH和胆盐浓度与脂肪消化和抗氧化活性相关,pH 7,胆盐浓度为10 mmol·L-1时,脂肪消化效果更好;胰脂酶浓度越高,脂肪和蛋白质消化率越高。因此,EPI人群可适量摄入补充益生元、胰酶制剂,提高对山核桃制品营养素消化利用率。

| Abstract: | This article explored the effects of different intestinal conditions and particle size on in vitro digestion of processed Carya cathayensis Sarg.(CCS), matrix degradation rate (MDI), digestibility of fat and protein, total phenols and antioxidant activity of processed CCS were analyzed under different bile salt concentration, intestinal pH values and pancreatic lipase concentrations according to the intestinal conditions of healthy adults and people with exocrine pancreatic insufficiency (EPI). The results showed particle size had the most significant effect on processed CCS in vitro digestion, and the MDI, antioxidant activity and digestibility of fat and protein of small particle processed CCS were higher than those of large particle processed CCS. The pH and bile salt were associated with fat digestion and antioxidant activity. When pH value was 7 and bile salt concentration was 10 mmol·L-1, the fat digestion effect was better. The digestibility of fat and protein would be high when the concentration of pancreatic lipase was high. Therefore, people with EPI can take in the appropriate amount of prebiotics and trypsin preparation to improve the nutrient digestion and utilization rate of CCS products. |
